This page introduces how to check whether your NVIDIA GPU card is CUDA enabled, and whether the latest NVIDIA drivers are installed.
CUDA Compatible Graphics
TUFLOW GPU requires an NVIDIA CUDA enabled GPU. To check if your computer has an NVIDA GPU and if it is CUDA enabled:
- Right click on the Windows desktop.
- If you see “NVIDIA Control Panel” or “NVIDIA Display” in the pop up dialogue, the computer has an NVIDIA GPU.
- Click on “NVIDIA Control Panel” or “NVIDIA Display” in the pop up dialogue.
- The GPU model should be displayed in the graphics card information.
- Check to see if the graphics card is listed on the following website: https://developer.nvidia.com/cuda-gpus
Updating NVIDIA Drivers
It is likely that the NVIDIA drivers will need to be updated to the latest version as the drivers shipped with the computers are usually outdated.
- Access the NVIDIA Driver Downloads (by following this link: https://www.nvidia.com/Download/index.aspx).
- Enter your GPU details, and click Search:
- Download Updated Driver and run Executable:
NOTE: Even if not prompted by the system, a restart is recommended to ensure the new drivers are correctly detected prior to running any simulations.
